Enclosed Weld Heads provide complete inert gas protection of the full weld bead circumference (an industry requirement for producing welded joints in electro-polished and hygienic applications). Collets are required for each tube diameter to be welded.

‘Fusion’ applications only, filler wire cannot be used with these heads. Welding will be made after preparation of the tube ends to provide a flat, square face. During welding the weld head remains static, only the rotor carrying the electrode rotates in an ‘orbital’ motion around the tube.

Our range of OSK weld heads are unique in design, the cable and handle/motor assembly is separate from the weld head itself, so one handle assembly can run a variety of different sized weld heads. This concept provides significant cost savings on multiple weld head systems and unmatched flexibility using the same weld heads on different manufacturers´ power supplies.

Four versions of the OSK welds are available:

Compact Gas Cooled, Gas Cooled, Water Cooled and High Duty Water Cooled

OSK GAS COOLED WELD HEADS

OSK-G Handle Assembly

The OSK G Handle Assembly comprises a handle, weld head interface, motor, gearbox and tacho/encoder unit with 8mtr long cable.

OSK G Handle and Cable Assembly, Item No. 1.3.2002

The OSK-G Handle can be used in conjunction with any of the following weld heads:

Gas-cooled weld head for applications with extremely narrow space requirements such as that seen with the 'microfit' component class in the semiconductor industry. Specially designed to weld micro-fittings. Unique construction, including specifically directed gas routing to improve gas coverage and careful material selection resulting in a high duty cycle even without water cooling.

For the highest duty cycle applications we can offer the gas-cooled OSK G series (starting from the OSK 53 G size) in a water cooled version (critical dimensions remain the same as for the gas cooled version). Full water cooling of the lower clamp housing. Also available as an upgrade for standard OSK G Weld heads.

Only one OSK-GW handle and cable assembly is needed for all OSK GW weld heads.

OSK GW/HD Handle and Cable Assembly, Item No. 1.3.2004

Consisting of a handle, weld head interface, motor, gearbox and tacho/encoder unit with 8mtr long cable.

Even though the OSK-G weld heads are the narrowest available some short 'stick out' applications require the ability to move the electrode position to one side of the weld head, this accessory provides that function in a simple and easy to use device.

Gas-shield collets are especially narrow and made from heat-resistant material for welding fittings, flanges, elbows etc. In combination with offset and multiposition electrode holders the weld can be completed very close to one side of the weld head. Special wide clamps are available for improved single side location on request.

Solutions to operate Orbitec weld heads in combination with other manufacturers equipment, e.g. AMI, Polysoude and Orbimatic are available for purchase and rental. Depending on the power supply to be used a simple cable adaptor or a complete handle assembly may be required, we have options to suit most applications, please contact your local office for further details.
